TITLE: On the Problem of Influence of the Armature -Circuit Inductance of a "Generator -Motor" System Upon the Transient Phenomena (K voprosu o vliyanii induktivnosti yakornoy tsepi sistemy "generator-dvigatel, na perekhodnyye protsessy) PERIODICAL: Nauch. zap. L'vovsk. politekhn. in-t, 1955, Nr 34, pp 129-138 ABSTRACT: In the analysis of transients, it is assumed that both the generator and the motor are equipped with compensating -field windings and that the generator magnetic circuit is not saturated. Furthermore, at variance with most published investigations, the armature -circuit inductance is assumed to be L 0-0. The operational differential equations set up for the case of a unit impulse at the system input are solved by the Laplas transformation. Transient curwent and transient rpm of the motor (dependent on time) serve as solutions of the equations. An analysis of the solutions shows that an oscillatory Card 1/2 SOV/112-57-5-10298 On the Problem of Influenc e of the Armatur e -Circuit Inductance of a I 'Generator - phenomenon can arise if 4T >6 , where T is the electromagnetic time constant of the armature circuit, (9 is the electromechanical time constant of the motor. The above expressions have been used for calculating motor current and rpm curves plotted against time for a system that has the generator field-winding electromagnetic time constant TV a 2.72 sec, 0 - 0. 0424 sec, and T of four alternate values: 0. 0050, 0. 0 106, 0. 050, and 0. The investigation has shown that two different effects of the inductance should be distinguished: that of the mechanical transient, i. e. , on the motor rpm curve, and that of the electrical transient, i. e. , on the armature -circuit current curve. While the firat effect is insignificant, the second is es.sential and is more pronounced for lower ratios of Tv/T. Thus, in the above calculation with Tv/T - 2. 72/0.05 = 55, the deviations of current curves with and without an allowance for the inductances are as high as 50% at the initial portion of the transient and as high as 2076 in the maximum-values region. At the same time, the rpm curves for both cases practically coincide. Card 2/2 CHERNYK, M.A... Electromagnetic time design constant of a d.c. machine and methods for decreasing it.

The Dergachev Machine Tractor Station of the Saratov- Ablaelt together with the Kolkh02'Imeni Kalinin carried out a complex utilization of run-off waterg in which the following points were taken into considerationt 1, Reducing of run-off water and retain- ing of snow by means of deep contour plowing in connection with plowing of parallel flat ridges. 2. Construction of dame for regular irrigation- 3- Building of dams for flooding of estuaries (liman). These water conservation measures increased the yields considerably, reduced soil erosion and were inexpen- sive as compared with large scale irrigation projects.

The author first for short assumeo that the central surface of the shell is bounded by a closed line with the curvature a, a const. Besides the prob- lem is considered unidimensional and Poissun (Puasson)'s coeffi- L cie t equal to zero. The notution was tal -en over from V. V. No- V022 ov (reference 3). The generalized Hook (Guk)'s law valid for this case and the functions of tension U, V, Yr (functions of Lurlye-Golldenveyzer) are given. Then the author gives expressions for the complex displacements and strains. On the edge, as is the custom, the moments of stress gene3alized -according to Kirchhoff (Kirkhgof) or the generalized components of the deformatiun of the vector of the torsion of the boundary element are given. The 4 quantities given here cowpletely dett~rmine the deformation of the boundary element. Especially the conditions for a stiff edge are given.

Two boundary conditions are investigated here: 1) static-,,eometrical quantities are given on the edge. Then in conjugate problems tile boundary conditions go over to conjugate conditioi-,c. Especially the conditions of the stiff edde then go over into the conditions of the free edge. 2) in the fundamental problem the displacements u - uO, v - vo w = w0, t$0 are ~,iven on the edge. The fixing conditions u-v.w= 40 go ov~~r to the c~)nditions of the free edge. The properties discussod here are closely connected aith the static -geometrical analogy and aake it possible imZediately to virite down the solution of the conjugate problem when the solution of the fundamental problem is knoin. When the boundary conditiona are formulated in a complex foria, the boundary oonditioiis of the conjugate problem are of the same type. In this sense sucif a problem Lmy be called a col-ijugate one. The simplifying limitations assumed here may without great difficulties also be omitted. There are 3 Slavic references. PRESEINUDs 11~ay 23, 1957, by V. I.

In the -perrforma-nee of the calculation the formulation of the transition conditions between the simpler parts then is usually difficult, since the complex functions have to be de- composed into their real and'imaginary parts. In the present paper the author avoids this difficulty by formulating and calculating the real boundary conditions as a variational problem. He introduces the notion of the complex energy and proves a minimum property of its moduluo. In the calculations it is assumed that the boundaries of the shell coincide with principal lines of curvature, furthermore the Poisson coeffici ent is set - 0. For a material of shells satisfying the law of Hooke then the equations following from the con- ditions of equilibrium and from the conditions of compatibil- ity are set up* Card 1/2 The very complicated general equations are simplified for the On a Variational Principle in the Complex Theory of 40-22-2-11/21 Shells case of two symmetrically loaded shells of revolution of equal thickness which are connected with each other along a parallel circle.

The author's exposition of the linear theory of shells includes a number of special features. The relations of the theory of shells are successively derived from the equalities of the three-dimensional theory of elastT-cit- jrelated to a triorthcg- o n a-1 system. of coordinates connected with the middle of the shell surface. A further development of V. V. Novozhilov's complex method is used in the exposition. The membrane solution Is re- garded as a particular solution of the general problem of moments.

The most difficult ptoblem of the present time is the determination of the applicability of the momentless theory and an estimate of the accuracyof the momentless solution. The present paper deals-with the following two questions; (1) When is it possible (or necessary) to use a momentless solution in exchange for a particular solution by the moment method, (2) For what kind of conditions can the momentless solution provide as full a solution, in terms of generality, as the moment solutio,'n.

Industrial .scintillators produced by the Irkutsk Chemical Canbine were studied. T~-_ specimens included both inorganic (NaIeTl Csl*Tl and KI-TI) and 9 yorganic (stilbene,?toian, naph thalene, anthracene) types and a plastic scint'llator4Ppacked with magnesium oxide re ,flector. It was found that thallium-activated sodium iodide is the best scintillator UDC: 539.16.07 .,d 1/2 L 2 AC.C NRt AP60107815 for counters operating in plateau conditions. A scintillator made of this material measuring 30 mm in diameter and 20 m long has a resolution of 18.5% with respect to CS137. The length of the plateau is practically independent of the radiation energy when these crystals are used for.recording y-radiation with an energy of >60 kev. A reduction in the length of the plateau is observed with a decrease in energy below this.point. CsI-T1 and KI-T1 crystals show a satisfactory plateau for specimens with a diameter less than or equal to that of the photomultiplier and a length less than or,equal to V2 the diameter* These crystals have a luminescence yield of 0.9 or more. -A comparison of the results of measurements on the FEU-35 and FEU-13 photomultipliera showed that the relative length,of.the plateau for the FEU-35 is approximately twice that for the FEU-13 with the same-type scintillator. --SUB CODE: 16/ SUBH DATE t~~,: 06Jan65/ ORIG REF 001/ OTH REF, _-002 I;,C rd 2/2 WAS STUKACH, A.

Impact tests approximated the service conditions during hot rolling. 2.5 mm long'cylindrical specimens with a 20 mm diameter-were reduced by 50% at a rate of deformation of 10 M/sec A 60-ton friction..press was used in combination with an electric fur-' nace equipped with a Silite resistor. A study of the hardening dia: grams showed that the hardening curves ascend sharply at low temper atures for most of the speci.6ons submitted to increased deformation. Card ACCESSION NR: AP40297o6 This shape of the curves is characteristic of high-melting and complex alloys. Low-melting resistant alloys show a peak which falls, off as the degree of deformation is increased and deformation re- sistance declines (zinc) "BrBZ bronze alloy). For "L62" brass and copper the work hardening is eliminated above 700C owing to'the high rate of recrystallization. These findings stand in good agreement iwith the results obtained by other authors. Bronze alloy "BrOts4-3" and "BrKDlff specimens were reduced at a rate of 0.045 m/sec in.a series of static tests. This tremendous increase in the rate of deformation resulted in an increased specific pressure and, conse- quently, the deformati:6n resistance of "BrOTs4-3" specimens was tri- j pled. The same dependence was observed 'in "BrKD1" specimens'. The results of static tests showed their unsuitability for the calcula- tion of the industrial processes which occur at high rates of de- ;:.-formation. Changes in the rate of deformation by about 1.5 to 2 Itimes do not affect the deformation resistance. Thereforal the spec-":- tific pressures obtained at a 10 m/sec rate are applicable to similar rates.

Some equipment of the petrolep industry has to operate at temperatures of 400 to 5~O C with pressures of 325 and 700 atm. in presence of hydrogen and other gases. Under such conditions the material is in a state of creep and several instances are known in which sudden brittle failure of the steel of such apparatus occurs after long duration operation in presence of hydrogen under pressure. It was found that the metal in such apparatus became brittle and decarburized. This problem has been extensively investigated in numerous countries. According to Class (Ref 10), the rate of decarburisation is Card 1/7 proportional to the stress in the tube walls, the long SOV/139-58-4-16/30 Long Duration Strength of Certain Steels Subjected to the Pressure of Hydrogen and Nitrogen duration strength of tubes in the presence of hydrogen under pressure is lower than in presence of nitrogen under pressure, also,addition to hydrogen of moisture and other gases affects the long duration strength of the steel. On the basis of analysis of published wonk and taking into consideration experience gained in hydrogenation plants in 1955, the Irkutsk Branch of NIIKhDAMASh decided to investigate the influence of gaseous media on the long duration strength of high temperature steels. The basic aim of the investigations was to determine the limit long duration strength of such steels in a gaseous medium to obtain more accurate stressing data, since such data are not available either in Soviet literature or in foreign literature. The second aim of the investigations was to study the nature of the action of hydrogen in steel in the state of slow plastic deformation. Solving the main task necessitated establish- ing the influence of hydrogen on the long duration strength at various temperatures and pressures and various stress Card2/7 states. The choice of the test rig was such as to obtain test conditions for the metal resembling as closely as SOV/139-58-4-16/30 Long Duration Strength of Certain Steels Subjected to the J>ressure of Hydrogen and Nitrogen possible those pertaining to the hydrogenation equipment and particularly to the tubes. The through flow of hydrogen was provided for removing corrosion products (methane) which may appear as a result of the interaction of hot hydrogen and the steel. For elucidating the influence of hydrogen pressure on the properties of steel under creep conditions and for determining the long duration strength of the tubes under the pressure of the media being processed, an original pilot plant set-up was produced in accordance with a design patented by one of the authors of this paper (Ref 15), a diagrammatic sketch of which is shown in Fig.l. The equipment was designedwith the following considerations in mind: there should be a possibility of testing the tubes under conditions approach- ing normal operating conditions, i.e. the flai must be ensured of various media through the tubes; it must be possible to investigate the tubes at various temperatures, pressures and with various media; it should be possible to Oard3l? ensure long duration operation at a given regime maintain- SOV/139-58-4-16/30 Long Duration Strength of Certain Steels Subjected to the Pressure of Hydrogen and Nitrogen ing accurately the temperature and the pressure; it should be possible to test simultaneously several specimens under mutually independent test conditions; the test rig must be safe to operate. The hydrogen or nitrogen is fed from a 600 atm industrial system through valves into a vessel intended for equalisation and for inter-mixing the gases, whereby the pressure is recorded on a self-recording pressure gauge. The gaseous medium is made to flow from this vessel into a collector vessel which feeds simultaneously six tube specimens each of 1000 mm length and an external diameter of 14 to 35 mm. The specimen is placed into a chamber furnace representing a protective tube of the heat and hydrogen resistant steel E1579. The temperature is automatically maintained at a desired value. The chemical compositions and the mechanical properties of the investigated steels are given in Tables 1 and 2. The measured times to failure as a function of the stress are graphed in Fig.3 and entered in Table 3. By extra- Card4/7 polation of the graphs, the limit long duration strength SOV/139-58-4-16/30 Long Duration Strength of Certain Steels Subjected to the Pressure of Hydrogen and Nitrogen was determined for the steel EI579 subjected to the pregsure of hydrogen and nitrogen; for a temperature o~ 550 C and a pressure of 600 atm these values (in kg/mm were as follows: after 10 000 hours - 17 for hydroSen and 24 for nitrogen; after 100 000 hours - 7 for hydrogen and 16 for nitrogen. Fig.2 shows the outside view of tubular0specimens of the steel 3OK12AA after fracture at 550 C caused by differing long duration load conditions; Fig.6 shows a photograph of an oval tube of the Steel 20 which failed after 2 hours at a hydrogen pressure of 600 atm at 500 C. Figs. 4 and.5 show micro-photos of the structure at various states of the material. The results of the work are summarised thus: 1. A test rig was built and tested which is intended for investigating the long duration strength of tubes under pressure produced0by any flowing medium at temperatures between 0 and 700 C and pressures up to 1000 atm. This set-up enables investigating pieces of tubes as well as welded tubes to determine the long duration corrosion Card5/7 strength under the influence of the pressure of a SOV/139-58-4-16/30 Long Duration Strength of Certain Steels Subjected to the Pressure of Hydrogen and Nitrogen flowing medium. 2. Testing the long duration strength of tubes under the effect of the pressure of a flowing medium Dermits determining more accurately the qualitative and quantitative indicesfbr operation of tubes under normal operating conditions (strength, corrosioni diffusion), 3. The long duration strength of tubes made of the steels E1579, ~OKWA and Steel 20F lower if subjected to hydrogen under pressure than if subjected to nitrogen under pressure and the difference increases with the test duration, as can be seen from the values quoted above. It was established that an increase in the stress of the tube wall brings about an increase of the speed and depth of decarburization.
